AirTran is currently investigating a pilot suspected of being legally intoxicated before his Saturday flight.

The pilot, who was flying out of Minneapolis-St. Paul International Airport, was arrested and removed from his flight to Milwaukee.

The flight was delayed 35 minutes, but later resumed with a replacement pilot.

A TSA manager at Minneapolis-St. Paul was the first to suspect that the pilot was intoxicated. According to an airport spokesperson, a TSA manager smelled alcohol on the captain and alerted airport police.
